Availability: OpenAI still prices the bare gpt-5-nano alias per token on its own rate card and announces no shutdown date for it. The pinned snapshot gpt-5-nano-2025-08-07 is separately scheduled to shut down on December 11, 2026; that date applies to the pinned snapshot, not to the gpt-5-nano alias, so this row carries no shutdown date. If OpenAI later names the bare alias itself, this row ages to Deprecated on that date. Checked against OpenAI's deprecations page on 2026-08-25.

Benchmark performance

accuracy % · higher is better
Percentile vs all tracked models 33.2th1 independent measurement
Percentile per $/Mtok 237.1

We hold no per-benchmark accuracy scores for this model yet, so it has no accuracy average. That is a gap in our coverage, not a sign the model is untested — independent evaluators often publish a composite index for a new model long before releasing its per-benchmark numbers. The percentile above is its standing across the independent composites below.
